Abstract

This memo introduces a domain and supplier independent generic architecture for information brokerage, designed as part of the ACTS project GAIA (Generic Architecture for Information Availability).

1. Introduction

Today a huge number of goods and services are offered on the electronic market by a large, and ever-increasing, number of suppliers. However, there is still no efficient way for a customer to find a product or information, he/she is interested in and a supplier that can provide that product. Customers and suppliers already can not deal with the quantity of available information by themselves. The high heterogeneity of existing protocols, formats, and underlying networks also limits development of the electronic market.

This results in a demand for brokerage systems that can work as intermediary entities between customers and content suppliers. Brokerage systems assist a customer during the trading process and hide the heterogeneity and distribution of information from the customer. The design of domain and supplier independent generic architecture for such brokerage systems is an objective of the project GAIA (Generic Architecture for Information Availability). GAIA received part funding from the EU ACTS programme for Research and Technological Development. The GAIA brokerage system allows a customer to

- search for a particular "product" (information, content or services) that he/she is interested in - locate the product, i.e. find supplier(s) from whom the product is available - order the product from the supplier - receive delivery of the product by digital means

All these actions are carried out by the broker in response to requests from the customer. Broker services are accessible to the customer through the unified user interface. The customer system does not have to support all the protocols involved in the trading process.

Full specification of the GAIA Architecture is available in the GAIA Standard [1]. The GAIA Standard includes a description of the GAIA Reference Model, GAIA Functional Architecture, GAIA Standard Profiles, and specification of the GAIA interfaces.

This memo does not aim to include the whole text of the GAIA Standard, but to present the basic ideas and concepts of this standard.

The structure of this memo follows the structure of the GAIA Standard:

1. The GAIA Reference Model provides a common basis for the description and specification of brokerage systems, including the GAIA system.

2. The GAIA Fu...
